Overview of this book

Blockchain and Hyperledger are open source technologies that power the development of decentralized applications. This Learning Path is your helpful reference for exploring and building blockchain networks using Ethereum, Hyperledger Fabric, and Hyperledger Composer. Blockchain Development with Hyperledger will start off by giving you an overview of blockchain and demonstrating how you can set up an Ethereum development environment for developing, packaging, building, and testing campaign-decentralized applications. You'll then explore the de facto language Solidity, which you can use to develop decentralized applications in Ethereum. Following this, you'll be able to configure Hyperledger Fabric and use it to build private blockchain networks and applications that connect to them. Toward the later chapters, you'll learn how to design and launch a network, and even implement smart contracts in chain code. By the end of this Learning Path, you'll be able to build and deploy your own decentralized applications by addressing the key pain points encountered in the blockchain life cycle. This Learning Path includes content from the following Packt products: • Blockchain Quick Start Guide by Xun (Brian) Wu and Weimin Sun • Hands-On Blockchain with Hyperledger by Nitin Gaur et al.

Introducing transactions


Our journey so far has involved understanding the fundamental nature of a business network—that it is comprised of participants involved in the meaningful exchange of assets. Let's now focus on the most important concept in business networks—exchange.

Change as a fundamental concept

Why is exchange the most important idea? Well, without it, participants and assets have no purpose!

This seems like an excessively hyperbolic statement! However, if you think about it for a moment, participants only meaningfully exist in the sense that they exchange goods and services (collectively known as assets) with each other. If a participant does not exchange with another participant, they don't exist in any meaningful way. It's the same with assets—if they aren't exchanged between participants, then they don't exist in any meaningful way either. There's no point in an asset having a life cycle if it doesn't move between different participants, because the asset is private to a participant...
